1 In the embodiment illustrated on the annexed drawings and hereinafter described by way of example, the change computing and distributing device of this invention is embodied in a keyoperated cash register of well known construction comprising, for each numerical order of figures providing the amount to be cashed or collected, a setting member or quadrant adapted to be shifted through predetermined angles under the control of selectively manipulated setting' keys and under the actuation of the main shaft of the register. The apparatus of this invention may also be embodied in lever-operated cash registers in which each setting membervor quadrant 40 is actuated directly or indirectly by a lever or handle, as well as in cash registers of both keyand handle-type in which said setting members are arranged for rectilinear operation through different extents instead of for oscillation through different angles.

As an illustration of this class of registers reference is made to British Patents Nos. 5,238/ 1891, 18,079/1892, 9,400/1897, U. S. Patent No. 580,378, French Patents Nos. 551,417, 616,322.

In the present specification, only the parts of a conventional cash register which cooperate with the apparatus of this invention are illustrated and described, such parts comprising for each numerical order or ordinal place (that is for units,

tens, hundreds and so on as well for tenths and hundredths respectively) a figure setting gear including aquadrant I loose on. a transverse shaft 2 and having teeth 3 which actuate devices belonging to conventional cash registers. Said devices are shown diagrammatically by 4 in respect of an indicating device. by 5 in respect of driving shafts actuating a printing device and by Sas a totalizing device, these parts being popular in the art and having no interest in this invention.

On each quadrant I a radial rod 9 is mounted to move by means of l two links 1 fulcruxned on said quadrant at 8 and providing a four bar linkage, the outer end of said rod 9 being thus able to engage any of notches I0 of a stationary plate fast on the bed frame I2 of the cash register. The rod 9 has at its internal end a tooth I3 able to engage a tooth I4 of a driving quadrant I5 solid with shaft 2, this shaft being oscillated, at a proper time during the register operation, by means of arm I6 and bar I1, these parts being actuated in turn by an arm |22 (Figures 2 and 12) loose on spindle 35 and by a cam |20 and a counter-cam I2I fast with the main cam shaft 28 of the register.

As shown in Figures 2 and l2, said main shaft 28 is driven by 'a handle |08 by the intermediate of pinions |09 and IIII to make two complete revolutions at each operation, the handle ||J8l being actuated by the operator to move through one complete revolution at each operation.

An arm i9 fulcrumed at 20 on quadrant I is pivotally connected at I8 with rodi! and the head i9 of said arm i9 is operated by a return spring 2| acting to move rod 9 towards quadrant I5.

As conventional, a row of keys 25 cooperating with quadrant I is arranged around said quadrant, they being mounted to reciprocate radially in stationary plate II.

On arm i9 is fulcrumed at 22 a pawl 23 having a return spring 24 and acting on arm I9, I9', said pawl 23 on impinging against the one of keys 25 which has been manipulated, causing the arm I9 to rock in opposition to spring 2| and to shift the rod 9 radially outward to carry it into engagement with one of notches I of stationary plate II. As understood and conventional, the keys 25 above referred to cooperate with the quadrant I for positioning it in accordance with the figure to be set in its ordinal place or .numerical order and the end of that of said keys 25 which has been manipulated in said row extends inthe path of pawl 23 during the oscillation of quadrant I carrying it.

vAbutments 2B of driving quadrants I5 operate to return respective quadrants I in their zero position in which their pawls 23 are engaged with a stop 21 which is released automatically when a key 25 representing a signicant figure is manipulated in the respective order. This operation is effected by a conventional device of the kind illustrated in Fig. 4 of French Patent No. 551,417 whose pawl 35 corresponds with stop 21 of the present application.

In the operation of the cash register as a Whole, as conventional and well known in the art, after keys 25 have been manipulated in the several ordinal places, the main cam shaft 28 which carries out the register operation is actuated and it causes the shaft 2 and driving quadrants I5 to oscillate rstly in anti-clockwise direction and then in clockwise direction, this actuation being effected by cams |29, I2I of shaft 28,

lever |22, bar I1 and arm Il as hereinbefore described. In said anticlockwise oscillation the abutments 2l of driving quadrants I5 carry all quadrants I in their illustrated zero-position while at the beginning of the second or clockwise oscillation in all the quadrants I in respect of which a key 25 has been manipulated and stop 21 has been removed, the respective arm I8 under the action of spring 2| carries rod 9 with its tooth I3 into engagement with tooth Il of driving quadrant I5. During this clockwise oscillation said driving quadrant I5 drives the respective quadrant I by the intermediary of teeth I4, i3 and rod 9 until the respective pawl 23 engages the end of the key 25 which has been manipulated in the respective row; then the rod 9 is shifted radially outward to release quadrant I5 and engage the respective notch I0 of stationary plate II. Thus the quadrant I is stopped after it has been moved through an angle corresponding with the figure or numerical value aillxed to the key 25 which has been manipulated in the respective row.

As above intimated a quadrant and a row of keys 25 with cooperating parts are provided in respect of each ordinal place of the item or amount to be set in by the manipulation of keys of several rows, and all said quadrants I are operated in the described manner by the actuation of cam shaft 28 to reproduce by the several angles they have moved through the amount or item set in by the manipulation of keys 25 in several rows.

In accordance with this invention the described operation in respect of each numerical order or ordinal place of the figures of the amount to be cashed, of a separate gear comprising setting members as keys 25 and a member as quadrant I which in the register opera tion moves through a defined space depending upon the particular figure set in the respective order, is availed of to set control means for change delivery. These control means include in each numerical order a cooperating member devoted to change distribution and which in turn presets the operation of change coin distributors and shares thereon the correct change on the basis of the monetary system to which the apparatus is devoted, While the actuation of said distributors is effected in the subsequent operation. Further the change coin distributor operation is made under the selective control of a further setting device (referred to in its whole in the claims as denomination means") which is preset, by a manipulation similar to the usual ones in cash registers, in accordance with the tendered money with respect to which the change is to be delivered, said last named setting device releasing from operation those of said distributors which must remain inoperative on account of the value of the tendered money.

As above stated in the embodiment of this invention as described and illustrated by way of example, it is assumed that the cash register includes four rows of cash setting keys 25.|, 25.2, 25.3, 25.4 corresponding with tens, units, tenths and hundredths respectively, each of said key rows cooperating with a quadrant as I. Further the apparatus includes a row of keys 51 for setting the tendered money and a cooperating quadrant R.| which is controlled and actuated in the manner hereinbefore described with respect to one of quadrants I.

In the embodiment of this invention in a handle-manipulated cash register, handles each spindle 29 in respect of each quadrant I each of,

said cams being connected in the hereinafter described manner with a pinion 34 in mesh with.

rack teeth I32 of the cooperating quadrant I. Each cam 30, 3|, 32, 33 includes a number of adjacent sections 30.I, 30.2, 30.3 solid with each other and each cooperating with a change coin distributor as hereinafter described. Each of said sections 30.I, 30.2 has on its periphery 1 recesses 30 and teeth 30' in accordance with the operation it must produce in the several respective distributors.

On a shaft 35 mounted to oscillate in the register bed frame I2 a frame is fast which includes side arms 36 and a transverse spindle 31 parallel with spindle 29 and fast in arms 36. One of said arms 36 has a fork 36' having end rollers 38, 38 and actuated by a cam 39 and a countercam 39 solid with cam shaft 28 of the cash register at a lagging angle with respect to cams |20, I2I which cause the oscillation of quadrants I and, generally speaking, to the cams carrying out the conventional and well known operation of the cash register. a

Parallel levers 40 are fulcrumed on spindle 31 each of them lying in the plane of one of the sections of a cam 30, 3|, 32, 33; with each of these cams cooperates a number of levers 40 equal to number of sections of such cam and each lever 40 has a nose 40' in register with respective' cam section.

Springs 4I acting between a bar 42 fast in the ends of arms 36 and heels 40" of respective levers 40 act, when the frame 36-31 is rocked, to hold noses 40 of said levers 40 against the cooperating sections of respective cams 30-33, While opposed arms of levers 40 normally abut on a stationary transverse bar |24.

Each lever 40 has a pin 43 at its eiid remote from nose 40' said pin 43 being able to engage a hook 44' of a rod 44 mounted to move longitudinally by means of its slots 4,5, 46 and supporting means therefor as hereinafter described.

'I'he first one 45 of said slots is engaged by a pin 41 of an arm of a lever 48 solid with a shaft 49 and whose opposed arm 48' (Figure 4) actuates a rod 50 which operates a change coin distributor as hereinafter described. The other slot 46 of rod 44 is arranged to slide on a guiding control pin 5I carried by a fork arm 52 which is fulcrumed on spindle 53 and Whose opposite ends are actuated in the hereinafter described manner by a cam member 54 pertaining to the hereinbefore defined denomination means" (each including a cam and a countercam as shown by 54 A and 54 in respect of one of them in Figures 1 and Each rod 44 is able to oscillate around pin 41 under the action of arm 52 and pin 5I and said rod 44 is engaged by its hook 44' with pin 43 of lever 40 or is released therefrom in accordance with the position imparted 4to its cooperating arm 52 by cam member 54 and associate parts.

On its edge remote from hook 44 each rod 44 has a notch 44" able to engage a stationary bar 58 when said rod 44 is shifted away from its cooperating pin 43 due to the operation of the respective arm 52. Said bar 58 thus locks rods 44 against any undue movement when they are made inoperative.

'Ihe several twin cam members 54, 54 provide in their whole a single cam member also denoted by 54, they being all solid with a shaft 55 having a pinion 56 solid therewith. Said pinion 55 is driven by a quadrant LR which, as stated, is similar to quadrants I and is controlled by keys 51 corresponding with several moneys or denominations of the monetary system to which the register is devoted and in respect to each of which the change is to be delivered.

Therefore, after one of the keys 51 cooperating with quadrant IR has been manipulated at the time of operating the cash register, said quadrant I.R and pinion 56 move through a certain angle during the register operation and when the oscillation cf quadrant I.R is completed and before the change delivering mechanism is operated by cams 39, 39 of shaft 28 and parts 40, 44 and associated ones, said cam member 54 has taken a position corresponding with the tendered money or denomination in respect to which said mechanism is required to deliver the change as the difference' between such tendered money and the amount to be cashed or collected this amount having been set in the cash register by the operation of quadrants I under manipulation of setting keys 25 and actuation of cam shaft 28.

By the described operation, when cams 39, 39 cause the frame 36, 3l' to oscillate during the register operation, levers 40 are moved with their noses 40 against cooperating sections of cams 30, 3I, 32, 33 and those of said levers 40 whose noses 40' engage a projecting portion (as 30') of the cooperating section of cams 30, 3|, 32, 33, are caused to oscillate around spindle 31 thus producing an upward stroke (Fig. 1) of the cooperating rods 44 in respect of such rods which have not been released by the respective arms 52 from cooperating pins 43. On the contrary, those of said levers 40 whose noses 40 find recesses (as 30) in the respective sections of cam 30, 3|, 32, 33 leave their rods 44 inoperative even if the cooperating arms 52 have left said rods 44 engaged with respective levers 40 by pins 43.

Thus each. change coin distributor hereinafter described is caused to operate only when it has been left in operative condition by the cooperating section of cam 54 and has been actually operated by the respective section of cams 30, 3|, 32, 33.

Each change coin distributor (Figures 5, 6, 7) includes a tubular magazine 59 having a supply hopper 60 and a detent device actuated by a rod 50 and a two-armed crank lever 62 connected therewith and acted on by a return spring |25. Said 'detent device is intended to cause a coin to fall from its magazine into a delivery cup I19 at each operation and includes an ejector 6I operated by said lever 62 the hub 64 of this lever being loose on a concentric sleeve 65 and on a central spindle 66 carrying it.

Each shaft 49 is provided with an actuating knob 61 located at the outside of the cash regis-k position it has been moved into, said spring 1| being arranged to be thrown from either side to the opposite one with respect to the axis of pivot 59 due to the oscillation of arm 56.

The indicator 68, 10 is actuated by a reciprocatory rod 13 pivotally connected with arm 14 fast to the sleeve 55 loose on spindle 66 and within the hub 64 of the ejector actuating lever 62. Said arm 14 has a finger 15 which is able to enter the cooperating magazine 59 through a slot 16 and is gently pushed against the coins lying at the bottom of the magazine by a spring 11 located in an opening 18 of iinger 15 and abutting on a lug 19 of hub 64 of the ejector lever 62. Said lug 19 enters the opening 16 while providing for the free respective oscillation of finger 15 and lever 62.

At each operation of rod 50, the lever- 62 is cs cillated and ejects a coin by ejector 6I, the finger 15 being moved by lug 19 through spring 11 towards the coins existing in the magazine and being prevented by these coins from oscillating to actuate rod 13 and indicator 68, 10 while the lever 62 and lug 19 thereof may freely osoillate as permitted by the spring 11 intermediate said iinger 15 and lug 19. On the return stroke oi lever S2 said finger 15 is moved away from coins Within magazine 59 by lug 19 engaged in its slot 18 for the unrestricted and free down motion of coins in the magazine.

At the time of the delivery of the last coin or of one of last coins from magazine 59, the nger 15 being not longer restricted by said coins freely enters the magazine through slot 'i5 under the action of lever 62, lug 19 and spring "i1, and by the intermediary* of the rod 13 it causes the indicator 68, 10 to suddenly pass into its operativo position (as shown by Way of example in connection with the magazine illustrated at right hand in Figure 6) to obstruct the hopper G0 and hold the indicator 10 in a position to be Well in View to operator. At the time of lling the magazine again with coins the operator acts by hand an arm 68 and carries it again into its inoperative position in which itis resiliently held by spring 'i' i.

The organization of the change coin magazines and of the respective actuating cam members 30, 3l, 32, 33 is made having in mind the monetary system, the change delivering apparatus and the cooperating cash register are devoted to and the requirements said parts must comply with in view of said monetary system to provide for any combination as required to distribute any sum less than or, as a maximum, equal to the value of the highest denomination or money which may be tendered. The cam 54 controiled by the keys 51 for setting the tendered denomination is organized in such a manner as to put in operative conditions such change coil distributors as necessary to deliver in their whole a sum equal to the value of the tendered money or denomination. Figure 3 illustrates the organization of the several cam sections in connection with a decimal monetary system including moneys or denominations having respectively the values 0.05, 0.10, 0.20, 0.50, of unity or 1, 2, 5, 10, 20, 50 unity or unities, and assuming the cash register is built for dealing with transactions up to 99.95 unities with variations through 0.05 each. Further it is assumed that the change is to be distributed by automatic operation by coins of above denominations up to 20 unities inclusive each and up to a maximum total amount of 50.unities, changes involving more' than 50 unities being assumed to be completed by hand by the cash register operator by means of moneys oi.' 50. 100 etc. unities. Ot course the above stated values and conditions are taken as an example of a set of actual conditions oi use, but the range of the apparatus operation may be extended as desired and it may include automatic distributors dealing with metal coins or notes of 50 and 100 unities each and over, and thus the apparatus may be organized for automatically distributing changes up to 100, 500 unities and over.

'I'he set A (Figure 3) of keys 25.1, 25.2, 25.3, 25.4 illustrates the usual setting in keys of cash registers that is the keys devoted to set in the sum to be collected. In view of the above assumption as to ranges of the apparatus, this set includes nine keys from 1 to 9 (as 25.1, 25.2 and 25.3) in each column or ordinal place of tens, units and tenths, and a single key 25.4 in the ordinal place of hundredths that is a key 25.4 for the amount 0.05 which is the single one commonly used in trade in respect of such hundredths.

The row B of keys 51 is devoted to set in the value of the tendered money with respect to which a change is to be delivered, that is it includes a key for each of values 0.10, 0.20, 0.50, l, 2, 5, 10, 20, 50, no key being provided for 0.05 coins because no change may be required in respect of such coins under the above stated practical conditions of trade.

In Figure 3 section I illustrates diagrammatically the configuration and position of cams 30, 3i, 32, 33 corresponding with quadrants i of the cash register devoted respectively to ordinal places of tens, unities, tenths and hundredths (the lastone being restricted to the value 0.05 as above stated) assuming that all said quadrants I are at their zero-position. Said cams are divided each in sections as hereinafter described their hatched portions illustrating in each section a projecting portion (as 30') able to provide conditions for actuation of a cooperating change coin distributor While unhatched portions illus` trate recessed portions (30) which are inoperative With respect to said distributors. Numerals 9 marked in Fig. 3.1 along the side of respective cams denote their portions which are carried in position for cooperation with noses 40 of cooperating levers 40 when the respective quadrants (i) are positioned in the usual operation of the cash register to set in amountsv including numerals 0 9 in respective columns or ordinal places.

Figure 3.11 illustrates the arrangement of the sections of cam 54 corresponding with keys 51 intended to be manipulated in accordance with the tendered money and providing the essential part of the hereinbefore mentioned denomination means. It is assumed that quadrant LR cooperating with said keys 51 is in its zeroposition and hatched portions denote the operative portions of cam sections 54 (such sections being herein illustrated separately and identified by 54.1, 54.9) which provide for the operation of cooperating change coin distributors by leaving rods 44 coupled with levers 40. Unhatched portions denote the portions of said cam sections 54.1 54.9 which actuate the cooperating arms 52 to release rods 44 from levers 40 and put the respective change coin distributors into inoperative conditions.

The change coin distributors (as 59 and cooperating parts) are divided in a number of groups equal tothe number of cash setting quadrants I in the cash register (that is in four groups in the described embodiment) and each of said groups includes distributors of coins whose denominations belong to the ordinal of the respective quadrant, having in mind that in respect of each of certain denominations two or more magazines and distributors may be provided, they oper-1 ating independently from each other under the action of separate sections of respective cam. Each of said groups is actuated by a respective cam member 30, 3|, 32, 33 and each of these cam members 30, 3|, 32, 33 includes a number of sections equal to the number of distributors pertaining to such cam member.-

More particularly, the cam 30 cooperating with quadrant of tens includes three sections 30.0, 30.2, 30.3 adapted to actuate three respective distrlbutor's of coins of tens ordinal (one for 20 coins and two for 10 coins); cam 3| cooperates with units quadrant and has four sections 35.8, 3|.2, 3|.3, 3|.4 actuating four distributors of coins belonging to units ordinal (one for 5 coins, one for 2 coins and two for l coin); cam 32 corresponds with tenths quadrant and has four sections 32.|, 32.2, 32.3, 32.4 which operate respec tively four distributors of coins belonging to tenths ordinal (one for 0.50 coins, one for 0.20 coins and two for 0.10 coins) iinally cam 33 coB operates with hundredths quadrant and has two sections each operating a distributor of coins of hundredths ordinal (two distributors for 0.05 coins).

Quadrants I and |.R above referred to are not illustrated separately in detail each of them being identical with quadrant I illustrated in Fig- -ure 1 and having teeth as |32 meshing with one of pinions 34 and 56, respectively, illustrated in FigureZ in connection with cam members 30, 3i 32, 33 and shaft 55 having cam member 54 fast thereto.

The distributors of each group may deliver any combination of unities of the respective ordinals up to nine unities (inclusive) in respect of intermediate ordinals and to te'n unities (inclusive) for the lowest ordinal (values in this lowest ordinal being as above stated restricted to that of practical use in the same) in the highest ordinal all combinations are provided for up to the value of the highest value coin from which the automatic change delivery may be preset, less one.

Thus in the illustrated construction the following maximum total amounts may be obtained in the respective ordinals or columns: hundredth ordinal up to 10/100 (0.05+0.05); tenth ordinal up to 9/10 (0.50+0.20+0.10+0.10); unit ordinal up to 9 units (5+2-l-1-l-1); ten ordinal up to four tens (20+10-l-10) because as stated the automatic change delivery may be preset in respect of moneys of 5 tens but the group of this ordinal does not include a distributor of money of 5vtens they being assumed to be delivered by hand.

'Ihe unit of which the distributors of tenth, unit and ten ordinals are short is intended to be delivered by groups of lower ordinal and thus any group of distributors of a given ordinal together with the distributors of lower ordinal may deliver a full amount of 10 unities of said given ordinal. Thus the group of tenths with the group of hundredths gives 0.90+0.10=1; the group of units with groups of tenths and hundredths gives 9+0.90+0.10=10; the group of tens with those of units, tenths and hundredths gives As above intimated, amounts over that which the apparatus is able to automatically deliver, are completed by money delivered by hand.

Each cam 30, 3|, 32, 33 has such a configuration as in the several positions it may be carried into by its operating quadrant that is in respect of several amounts to be collected which may be set in the machine, it causes the delivery of the difference between the figure of such amount to be collected as set in unto said quadrant and the maximum total change the group of distributors of the same ordinal (respectively 40, 9, 0.90, 0.10) may deliver. The total of such differences is obviously the correct change to be delivered. By way of example, assuming that an amount of 14.25 is tobe collected, the several quadrants of the cash register at the time of the usual manipulation and operation of said register will set in the respective ordinals or quadrants the figures 10, 4, 0.20, 0.05 (total i425) and the cams 30, 3i, 32, 33 will have in iront of noses 40 of levers 40 their portions which in Figure 3l are respectively in register with lines I, 0, 2, 5. Assuming that all rods it are connected with respective levers 40 said cams .T0-33 at the time of the described operation will cause in the respective ordinals the delivery' of the above stated differences, that is Liii-10:30 (made up of 204-10); 9-4=5; 0.90-0.20=0.70 (made of 0504-020) and 0.10-0.05=0.05; as a total 30+5+0.70,'-0.05=35.75 which is the correct change over 14.25 to 50.

The several operative positions of the cam 55 setting in the value of the tendered money with respect to which money the described device is intended to deliver a change over an amount to he collected, or to deliver a change made up of coins of smaller denominations are shown by 0, 0.10, 5.20, 0.50, l, 2, 5, l0, 20, 50 in Figure 3H and are such as in each of them said cam 54 by means of its integral sections 51H 54.9 (Fig. 31E) brings in operative conditions such a number of distributors, beginning from those of lowest denomination, asrequired to deliver a total maximum amount equal to the denomination of the tendered money. By way of example, when a 20 coin is tendered, the distributors of 0.05, 0.05, 0.10, 0.10, 0.20, 0.50, l, l, 2, 5, 10, that is 20 as a total, are in operative conditions, While one of distributors of l0 coins and the distributor of 20 coins are made inoperative. In the event of the above suggested collection of 14.25 against a tendered sum of 20, the described device causes the delivery of coins only from those of the several levers 40 (that is 5+0.50+0.20+0.05=5.75 which is the change over 14.25 to 20) while no coin is delivered by the distributors which are in inoper` ative conditions (20 coin and 10 coin).

When cam 54 is in its position marked 50 in Fig. 3.11 with respect to levers 52 controlled thereby, all the distributors are in operative conditions through their respective rods 44 being coupled with levers 40. On the contrary, when said cam 54 is in 0.0 position all rods 44 are released from levers 40 and therefore all distributors are inoperative to deliver coins.

0f course, when the device is manipulated in accordance with a tendered sum but no cash is set in for collection (that is none of keys 25 has been manipulated), at the time the cash register is operated the described device will deliver the change in respect of a 0 collection, that is it will deliver the change of the tendered money or, in

' other words, the same amount as such tendered delivered there are one or more 0 at the right of the first significant figure (that is a figure being not 0) beginning from right hand, no coin is delivered in the ordinals in which said 0 appears or appear, and that the full amount to be dev livered is made up with coins of higher ordinals or denominations. Assuming'that the sum of 20 is tendered and the amount of 6 is to be collected, the change, that is 14.00, includes two 0 at the right of first signicant figure from right (4), such 0 belonging to ordinals of tenths and hundredths. Assuming the device to operate as above described, the change would be delivered by the following series of coins:

to secure the lastly stated conditions, on the con- For sucha purpose it is necessary that in the operation of the device the cams 32 and 33 of tenths and hundredths are carried in such a position as to leave the respective distributors inoprative, and the cam 3| of units must be carried in a position to deliver one unity over the number of unities it should deliver in view of the figure which has been set in its cooperating quadrant l by the 'respective key 25.

Such a condition is secured as hereinafter described by means causing such cams to move forward through one step as required for the above stated purpose bearing in mind that, generally speaking, those of said cams 30-33 which pertain to the ordinal of the first significant iigure from right and to the lower ordinals are required to move forward through one step.

As above exemplified, cam 3l must move (Fig. 3.1) from 6-position to 5-position (having in mind that the marking of these positions corresponds with the amount to be collected) -in order to deliver 4 unities insteadof 3, and the two cams 32 and 33 must move from 0-position to 9-position in which they cause no delivery of change coins. On the contrary the position of cam 30 must be unaffected.

When in the change amount there are zeroes at the left of a significant gure', the cams 30- 33 oi the ordinals in which said 0 appear and the cams of the ordinals higher than that of said significant figure are not to move forward. Say in the case a change involving the delivery of 10.50 (as the difference over a cash of 9.50 to be collected to a tendered sum of 20) assuming the device is operated in the first above described manner the change would consist of 10+0.20+0.10+0.10+0.05+0.05=10.50

To obtain the change by the minimum number of higher coins, the cam 33 (hundredth ordinal) is required to be moved forward through one step to make the distributors for 0.05 and 0.05 coins inoperative, and also the cam 32 (tenth ordinal) is to be advanced through one step to deliver one tenth more to cover lack of delivery of ten hundredths. Cams 30 (tens) and 3l (units) are not required to move forward they being in correct position. Then the change is delivered as follows: l0+0.50=l0.50.

To `secure the described operation the apparatus comprises a transfer gear operative on cams 30, 3l, 32, 33 which in the described embodiment operates as follows: when cam 33 is in its 0 position it causes cams 32 and 33 to move forward through one step; when cams 32 and 33 are in 0 position it causes cams 3|, 32, 33 to move forward through one step, and when cams 3l, 32 and 33 are in 0 position, it causes cams 30, 3l, 32, 33 to move forward through one step.

The apparatus further includes a control device able to cut of! at will the operation of the above stated transfer device in order to obtain the delivery of the change coins to be made in a series of coins of lower denomination, that is as firstly above described. Such a control device is actuated by a so-called change key as shown by 99 and intended to be manipulated by the operator when he desires to deliver the change of a tendered money and also, if and when desires, to deliver a change made up of a large number of coins of low denominations.

This provision in respect of a change key is necessary because in view of above described construction and operation, when the change delivering apparatus is operated without the operator having previously set in an amount to be collected by the manipulation of keys 25 (that is when all quadrants I corresponding with the amount to be collected are in their 0 position) and the said tens transfer device is left operative, all the cams 30, 3l, 32, 33 are in their 9-position (Figure 3.1) they thus making all the coin distributors inoperative. On the other hand such a change delivery operation without a cash to be collected being set in the register has no meaning because all existing key-operated cash registers include a locking -device which makes the cash register inoperative when no amount to be collected has been set in, as well as a change key which releases said locking device to provide for manipulations directed to deliver the change of money. In the embodiment of the apparatus of this invention in usual cash registers such an existing change key is availed of to cut off the operation oi' the tens transfer device above referred to in respect of cams 30,` 3|, 32, 33 when the cash register is to be operated in respect of a money change operation without any cash collection.

To secure the above described operation each of cams 30, 3l, 32, 33 actuating the coin distributors instead of being fast to its pinion 34 actuated by the respective setting in quadrant I and key 25, is loose on a hub 34 of said pinion 34 which in turn is loose on spindle 29 (Figures l and 8-11) and each of said cams 30-33 is angularly connected with the respective pinion and hub 34, 34' in such a manner as to be free to move temporarily through one angular step 75 with respect to it (said step being the angie included between two subsequent positions marked 0, 1 9 in Fig. 3.I). Such a lost motion connection is provided by a pin 80 fast on each hub 34' and entering a quadrant shaped recess 8| oi' the respective cams 30, 3|, 32, 33 while a spring 82 operative intermediate the pin 80 and the opposite front face of recess 8| tends to holdsaid cam in its angular position with respect to pinion 34 and cooperating quadrant I, in which such cam takes the positions illustrated in Fig. C I in respect o similar positions imparted to its quadrant I by the manipulation of the respective key 25.

Each cam 30-33 is further fast with a ratchet l pinion 83 having ten saw teeth and cooperating with a pawl 84 which is actuated in the hereinafter described manner. Said cooperating pawl 84 and ratchet pinion 83 when so actuated cause the respective one of cams 30-33 to move for- `ward through one step with respect to respective driving pinion 34 and bring such cam into a position corresponding with a completed transfer through one unity from each cam unto the adjacent one of a higher ordinal.

Each of pinions 34 actuating' the lower ordinal cams 3 I, 32, 33 is solid with a disk 88 loosely contacting with an arm 81, 81', 81" solid with a sleeve 85, 85" loose on a spindle 86 mounted and actuated as hereinafter described. The sleeve 85" corresponding with the cam 33 of lowest ordinal is solid with two pawls 84 actuating thevratchet pinions 83 of cams 33 and 32the second sleeve 05' is solid with pawl 84 actuating the ratchet pinion 83 of cam 3|, and the third sleeve 85 is solid with pawl 84 actuating the ratchet pinion 83 of cam 30. Said disks 88 have such a diameter as to hold the respective arms 81 in a lifted position in which they hold their respective pawls 84 out of engagement with respect to respective ratchet pinions 83, but each of said disks has a depression 88' in such an angular position as when the cooperating driving pinion 34 is in the position it has when cooperating quadrant I is in zero-position said depression 88 is in register with arm 81 to enable it to move down thus bringing the pawl or pawls 84 fast therewith into engagement with respective ratchet pinion or pinions 83.

The two sleeves 85' and 85 of higher ordinals have each an arm 89 which may be engaged by a pin 90 to lift pawl 84 and remove it from ratchet pinion 83, said pin 90 being faston hub 85" or 85 of the lower ordinal, while springs 9| act to return sleeves 85, 85', 85" with their arms 81 and pawls 84 towards disks ions 83.

The spindle 86 supporting the sleeves 85, 85', 85" of several pawls 84 and arms 81 has its ends fast on plates 92 solid with a hub |23 loose on stub shaft 35 fastened in the cash register frame bed; plates 92 also carry a bar 94 on which return springs 9| for said pawls abut. The frame consisting of hub |23, plates 92 and spindle 86 may thus oscillate around stub shaft 35 and is actuated by a cam and a counter-cam 95' of the general cam shaft 28 by the intermediation of a fork arm 96 loose on shaft 35 and having rollers 91, 91 -cooperatingwith said cams 95, 95'.

The interconnection of arm 96 with frame 92, 86 is provided, under the control of the operating key 99 (this corresponding with the changekey above referred to) by a gear including a lever |00 fulcrumed at |0| and actuated by said key 99, a bar |02 andla lever |03 pivotally con- 88 and ratchet pin-v nected with said bar |02 and loose on spindle 90 carried by one of said plates 92; said lever |03 has a pin |04 able to engage a notch |36 of arm= 96 and it also has a notch |06 adapted to engage a pin |01 fast on the register frame bed in order to lock lever |83 with its pin |04 out of engagement with arm 96.

When key 99 is not manipulated, the frame 92, 86 and arm 96 are interengaged and then cams 96, 95' on being driven into revolution by the cam shaft 28 in the general operation of the cash register cause said frame 92, 86 to oscillate; on the contrary, when key 99 is manipulated said arm 96 is held released from frame 92, 86 and therefore said frame is not oscillated in spite of the arm 96 being actuated whenever the cam shaft 28 is revolved, that is at each complete operation of the cash register.

The cams |20, I2| which produce the oscillations of quadrants and .R (whose angular strokes corresponding respectively with the cash set in by keys 25 for collection and the tendered money set in by keys 51 define the positions taken by several cams 30 3|, 32, 33 and by cam 54), the cams 95, 95' actuating the arm 96 and the cams 39, 39 causing the oscillation of the frame 36, 31 and therefore the operation of levers 40 which actuate the respective change coin distributors`are all fastened in such a respective angular position to each other on shaft 28 as when said shaft 28 is actuated through a single revolution at the tine the cash register is operated under the action of a driving gear (which in the illustrated embodiment consists of an operating handle |08 and pinions |09 and ||0 fast on said handle and shaft 28), firstly the quadrants I5 are oscillated which carry the quadrants I and I R and therefore the cams 30, 3|, 32, 33 and cam 54 in respective set up positions, then the arm 96 and frame 92, 86 are oscillated assuming that the parts 99-104 are in conditions to interconnect arm 96 and frame 92, 86 and finally the frame 36, 31 is oscillated it driving levers 40 with their noses 40' against cooperating cams 30-33 for the operation of the change coin distributors 6|.

Then, if the change key 99 has not been manipulated, immediately before the 'cooperation of levers 40 with cams 30-33 the pawls 84 cause those of cams 30-33 pertaining -to the ordinal in which the significant figure of lowest ordinal in the sum to be collected has been set in and to all lower ordinals to move forward through a step while the arm 81 cooperating with disc 88 of pinion 34 which has been actuated by the particular quadrant in which the significant i'lgure of lowest ordinal has been set in is lifted and makes its own pawl 84 inoperative (this pawl acting on the ratchet wheel 83 of the cam of the immediately higher ordinal) as well as, in view of the parts 90, 89, the pawls 84 of all the cams of higher ordinals even if in such higherordiy nals one or more disks 88 are in 0 position (as above defined in the description of operation of parts 88, 88', 81 and related ones) thus effecting a transfer in the above stated meaning.

In the above stated conditions the described operation is secured and then cams 30-33 of lower ordinals with respect to that on which the lowest ordinal figure has been set in are inoperative with respect to their distributors whilst said cam on -which the lowest ordinal significant iigure has been set in is moved forward through one step to compensate for the cams of lower ordinals having been made inoperative; as above demagazines 59 contain a supply of coins of respective denominations, keys 25 of the cash register are manipulated in the usual manner in accordance with the amount to be collected, that of keys 51 corresponding with tendered money is actuated and the main shaft 28 of the register is driven by means of handle |08 (a suitable motor beingl 'used in lieu of said handle if desired) to cause the said shaft 28 to rotate through a single full revolution it thereafter coming again at rest, as usual in cash registers.

Assuming the item 15.25 has been set in by keys 25 and that a 50 coin is being tendered and the respective key 51 has been manipulated, and further assuming that the change key 98 has not been operated, quadrants i, LR on carrying out their operation cause the cams 30, 3i, 32, 33 to take the respective positions in which their portions 1, 5, 2, 5 (Fig. 3.1) are in register with noses 40 of levers 48, while the cam 54 takes its {v0-position (Fig. 3.11) in which it leaves al1 the rods 44 coupled with respective. levers 40, and all pawls 84 are made inoperative; at the time the cams 38-39' actuate the frame 36, 31 said levers 40 are driven with their noses 40' against cams 30-33 and those are operated amongst them whose noses 40 have a projecting portion (as 30') in front of, while levers 40 are left inoperative whose noses 40' have recessed portions as 30 of cams 3|-33 in front of; thus such distributors as 6i as necessary to deliver the correct change (34.75) are actuated.

In the event that a money having a lower denomination than the maximum one for which the apparatus is organized is tendered, the cam 54 in view of the manipulation of the respective key 51 causes the levers 40 of a number of distributors to be released from rods 44 such distributors thus being left inoperative during the operation.

Finally, if the change key 99 has been operated, all pawls 84 are left inoperative and the change is delivered in a larger number of small denomination coins.

`If desired, the delivery of coins may be produced from desired magazines by manipulating the respective handles 61 and the signalling device 68, 'l0 is made automatically operative in respect of magazines 59 as soon as they are empty as described with reference to Figures 6 and '7.

The apparatus of this invention has been described in combination with a cash register and assuming it is actuated by setting in parts of such a register, but this apparatus may be actuated by the parts of a totalizing apparatus, the several pinions 34 which actuate cams 30, 3|, 32, 33 being then driven by respective pinions solid with parts of said totalizing apparatus in lieu of the setting quadrants of a cash register; then the change or difference will be delivered in respect to the sum totalized by said totalizing apparatus instead of being delivered with respect to a denomination set in the cash register at each separate operation.

Of course, instead of using cam members as 30-33 arranged and actuated as described, the apparatus may include cam members or equivalentmeans arranged directly on quadrants I,

LR or also reciprocatory members having cam portions.

Finally, the described device may be provided by itself with separate setting in means and actuating means in order to be used independently of other machines.
